I won't give you a step by step commentary on where I am in S3, but some eps drag to give you more background whereas others advance the story.
Some characters are gratuitously snippy, bitchy, sadistic and cruel. In some of them it seems forced but I digress. I really like the Diana Rigg character as she tells it like it is and that red witch is creepy. I feel bad for Arya as her childhood is going away, She has to grow up too fast.
I still stand by the dragonmom Dany and the formulaic storytelling I posted a few posts up.
I learned never attend a wedding reception in the show.
...and they save the most action for eps 9 and the finale.
All in all, a great show to watch in the winter when things are slow for me.
Next... season 4.
